Lovelace Entities Card - Type Conditional Wont Work

How does the entities card - type: conditional work? I’ve tried multiple variations of the following…

type: entities
entities:
  - type: button
    ...
  - type: section
    ...
  - type: conditional
    conditions:
      - entity: input_bool.test
        state: 'on'
    row: 
      card:
        type: entities
        entities:
           - entitiy: ...

I’ve been searching the forum and trying different things, indentation, remove card, etc, for over 2 hrs now. :confused:

This configuration works for me. Mind you: refresh the browser window, only after the refresh will the conditional card work properly.
In the vertical stack the top card is a custom select card (always visible), allowing to set an option (sure, no_way). Based upon the chosen option (sure) either the first conditional card (the button card) is shown that will trigger the reboot automation or (no_way) the second conditional card (the markdown card) showing the text to select the proper option above.

type: vertical-stack
cards:
  - type: 'custom:select-list-card'
    entity: input_select.rebootselect
    icon: ''
    truncate: true
    show_toggle: true
    scroll_to_selected: true
    max_options: 5
    title: Do you want to reboot?
  - type: conditional
    conditions:
      - entity: input_select.rebootselect
        state: sure
    card:
      type: button
      tap_action:
        action: toggle
      entity: input_boolean.restart
  - type: conditional
    conditions:
      - entity: input_select.rebootselect
        state: no_way
    card:
      type: markdown
      content: >-
        First select the option to reboot above, then the reboot button will show
